Hair Follicle Drug Testing - Gillis, LA

What it is, How it works

Hair testing has become recognized as a potent means for identifying drug and alcohol consumption. The fibers of a growing hair strand capture biomarkers, giving hair the ability to provide a prolonged history of substance use. When taken near the scalp, hair can reveal a detection timeline of about 3 months for alcohol and drugs. Hair collection is straightforward, less prone to adulteration, and convenient to transport.

A 1.5-inch segment, consisting of roughly 200 hair strands (comparable to a #2 pencil), taken nearest to the scalp, yields 100mg of hair—ideal for initial screening and confirmation. For EtG, additional tests, or panels beyond ten, it's advisable to gather 150mg of the sample. We suggest using a jeweler's scale for precise weighing. If head hair isn't available, an equivalent quantity of body hair can be gathered. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other types (e.g., facial, axillary).

Process Overview

The drug test laboratory process comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is first processed into the lab's system. This section ensures that the sample is correctly sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and addresses any missing data entry not captured by an electronic chain of custody.

Screening involves an initial drug assessment. Although Screening is a cost-efficient method for ruling out most drug usage, a positive result must be confirmed for legal acceptability. Presumptive positives in Screening necessitate further confirmation.

For samples marked as presumptive positives in Screening, additional hair is taken from the original specimen for Extraction. This phase involves withdrawing drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug screening.

Positive Screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, presumptive positive samples are cleaned as required. The full laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify substance use over 90 days, unlike urine tests which have a shorter period.
• Challenging to cheat: It is extremely hard to tamper with a hair drug test, thus ensuring accuracy in results.
• Records historical patterns: It offers insights into a pattern of drug use over time rather than just recent activities.

Limitations:

• Does not detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expenses: Hair drug tests tend to cost more compared to other testing methods.
• Result variation: Factors like hair color and unique hair growth differences can influence drug metabolite levels in hair.

Note: Often called "hair follicle tests", these tests analyze the hair strand, not the follicles beneath the scalp.
